The United States has long included merchant ships in plans to support Navy-Marine Corps Amphibious Assault Follow-On Echelon AFOE and Army Logistics Over-The-Shore LOTS operations. The shift toward port-dependent cargo ships has generated the need for the military to investigate other methodsfacilities to offload cargo without having to develop complex commercial type harbor facilities in the objective area. Military vehicular cargo such as the tanks, artillery trucks, trailers, and other rolling stock can be most efficiently transported to the objective area by the U.S. Flag Roll-OnRoll-Off RORO ships. The tests with the MV CYGNUS and SS ATLANTIC BEAR prove the viability of the RORO Discharge Facility concept for both offloading and backloading of self-sustaining and nonself-sustaining RORO ships in an offshore setting under calm water conditions. Representative military vehicles were driven from the ships onto Causeway Ferries and Landing Craft, Utility LCUs for transfer to the beach. Ship backloading operations were also tested by reversing the ships offloading sequence. Both ship tests, which were performed in conjunction with and during the Joint Logistics Over-The-Shore JLOTS II exercise, were designed to validate previously developed operational procedures and provide a means of further technical evaluation of the Navys RORO Discharge Facility equipment. This report documents the technical evaluation of the test events, evaluates the results, and provides concluding recommendations.
